Ulriken, Anna-Bergen Tunnel

Owner: Bane NOR
Norconsult AS turned to BIM for not only coordination and collaboration with design and construction of the new Ulriken tunnel in Norway, but also to create a fully immersive game and virtual reality experience. As Northern Europe’s most-trafficked single-track tunnel, the Norwegian railway between Fløen and Arna required increased capacity and safety. This meant boring through Mount Ulriken to build a new, parallel 7.8 km tunnel and upgrading existing stations that are already tight on space within two city centers. And this all had to be done without disrupting any of the current railway traffic.

Why has the old line Bergen - Arna via Nesttun, Helldal, Haukeland and Espeland been closed to traffic and deposed? This one has been an excellent relation from the suburbs to the centre Bergen.
